InCanada 21, 1934 1 Claim. (01. 229-11 My invention relates toimprovements in folding boxes with integral spouts, and has for anobject to provide a box blankfrom cardboard, crai'tboard, pasteboard, orthe like, with openings therein, cuts 'therethrough, scores thereon andshapes thereof, which is suitable for being folded into atlghtly-closable receptacle, and which is provided with a spout formedfrom the spout blank and foldable into spout shape while being extendedto its pouring positionto a stop thereon and also being withdrawable toits fiat shape wherewith the receptacle is closed.

Other objects of my improvement will appear as the description proceeds.

I attain these and other obiects of my improvement with the-mechanismillustrated in the accompanying sheet of drawing, whichforms a part ofthis specification, in which Figure l is a plan view of a box blank fromwhich a box with a m foldable spout may be formed, Fig. 2 is a top planview of the formed and pasted box, Fig. 3 is a repetition of Fig. 2 withthe detachable piece removed, Fig. 4 is the same as Figs. 2 and 3 withthe central portions of the outermost two layers of the material of thetop folds broken away, Fig. 5 is a side elevation of the box with thespout extended and stopped in pouring position, Fig. 6 is a frontelevation of Fig. 5, Fig. 7 is a plan view of the flattened spout piece,from which the rep mainder of the box blank is broken away, showingoptional closure stops thereon, and Fig. 8 is a plan view of the endfragmentary portion of the second top fold showing an optional shape ofthe closing flap.

Similar characters refer to similar parts throughout the several views.Certain parts are broken away to show other parts hidden thereby.

With more particular reference to designated parts:

In the drawing of the box blank shown in Fig. l the solid lines indicateeither margins or cuts made entirely through the material, while thedotted lines indicate scores or indentations to determine and localizethe places for bending the material when forming the receptaclestherefrom.

The box blank is substantially rectangular in exterior outline andconsists of the front side I, the rear end 8, the rear side 9, the frontend ll,

iii the first bottom fold II, the second bottom fold ii, the thirdbottom fold IS, the fourth bottom fold l4, the side flap ii, the firsttop fold ll, the second top fold II, the third top fold it, the fourthtop fold l6,-the spout flap 34, 35 and 36 and 5, the closing flap 41.While in Figs. 7 and 8 the optional closed-position stops are at (:34and all. and the optional closing-flap shape is shown at 4!, s41.

An opening 4| is cut through the fourth top fold I, an opening 45 is cutthrough the third 5 top fold II, and a deep notch 48 is, cut into theend of the second top fold Ii.

The corners of the box are formed on parallel dotted lines 20, 2|, 22and 23. The top folds are bent on the dotted line 24 and the bottomfolds 10 are bent on the dotted line 2!.

In addition'to the opening in the top fold It is the through cut-42. Theends of the opening 4| and the ends'of the out 42 are joined by thelines of through perforations 43 and 44. 15

The spout flap is partly severed from the top fold I! by thespaced-apart, aligned through cuts 32 and 33 and the intervening spaceis marked by the dotted line 1736 which is the locus of a hinge score.Centrally in the outer edge of the spout go flap is arcuate notch a theends of which are connected to the ends of the hinge score bl by thescores on the dotted lines it and 39. The side walls 40 and s40 of thespout have the arcuate edges 34' and 35, respectively, and the stop lugs31, 31 are attached thereto adjacent the cuts 32 and 33.

From the through bottom cuts 26, 21 and and the through top cuts 29, and3| narrow pieces of the material have been removed to pro- 30 videfreedom for the folded parts when forming the box.

The box is shaped and glued in the usual manner withthe number one topfold I! on the inside of the top cover, the number two top fold 5 I! onthe top thereof, the number three top fold I8 on the top of fold l9, andthe number four top fold It on top of the number three fold and on theoutside of the top of the box. The

four top folds are glued together except that the 40 center of thedetachable piece 48, which lays directly over the opening on flap It,the spout form and the flap 41 are not fastened by glue to the otherparts. The side flap I5 is glued to end piece It and the bottom flaps H,l2, l3 and 45 I4 are glued together, forming the bottom of the box.

with the box thus completed and filled, say

with salt, the top thereof appears as in Fig. 2. I When it is desired toremove the first portion or all of the salt from the box, the removablepiece 48 is torn away by catching fast to an edge thereof in the opening4| and tearing oi! the piece on the perforated lines 43 and 44. Then thetop of the box appears as shown in Fig. 3.-

To extend and shape the spout, insert the tine of a table fork, say,beneath the top flap M and, while lifting the flap with the tine, insertthe same beneath the spout end at the notch 42% and, by lifting upwardon the fork tine, extend the spout and form the same by drawing itthrough the opening 86 in the second top fold id. The extended andshaped spout will appear as in Fig. 5 and-Fig. 6 with the lugs37,3lbearing on the bottom surface of the second top fold it, wherebythe further extension of the spout is prevented and the spout is fullyopen standing in the deep notch Qt of the second top fold. To withdrawthe spout and close the openings in'the box top the spout is pusheddownward into the top of the box through the openings 65 and (it whenthe resilience of the material at the bends will cause the spout flapto'again u a nearly flat shape, closing the said openings. Fig. 4 isused to show the appearance of the box top after the spout is withdrawnthereinto. Here, the central portion of the two outer folds are brokenaway and the closing flap M is shown to be, not overlying the spout endas in Fig. 3, but rather beneath the spout where it serves to preventthe flattened spout from entering further beneath the box top, and alsoas a closure from within the cover to prevent the loss of salt throughthe box top in case the box be inverted. Furthermore, the particularlocation of the closing flap (ll, as shown in Fig. 4, provides afinger-nail-hold with which the subsequent extending of the spout isfacilitated. V

In the optional shape of spout blank, shown in Fig. 7, the closure stopadd is formed by a s boss extending laterally from the outer part of thespout side 2343 and the transverse through cut bid; and the closure stopa35 is formed from a small boss extending from the upper part of thespout side 35 laterally and the transverse through out 1735. When thespout is formed by being drawn outward through the opening 46, the saidlateral bosses flex inwardly and pass through the opening and thenassume again substantially the positions relative to the spout back 36'which they occupied when within'the box. Thus, when the spout iswithdrawn the lugs (:34 and ate protrude over the sides of the opening46 and engage with the box top to prevent the spout from fully enteringwithin the box. In the optional shape of the closing flap i'i shown inFig. 8, the notch ad! is not deep enough to leave uncovered an openingin the closed box but it provides for more easily inserting the saidopening tine.

I claim,-. v

A device of 'the kind described including, a card-board box, three topfolds glued together providing the top of the said box, a detachablepiece in the topmost of the said three top folds, the two top foldsbeneath the said detachable piece having openings therein registeringtherewith, a relatively shorter bottom top fold, a

spout blank integral with the said short box-top PAUL JOHNSON.
